Summary
This study investigates how genetic and environment factors operate over the life course to increase risk of adverse outcomes for children of women with severe mental illness. We examine the clustering of neuropsychiatric outcomes in families and individuals, the role of developmental adverse life events in the risk for these outcomes, and the children's physical morbidity and offending profiles. This is an electronic cohort (e-cohort), constructed by record linkage across many databases.

This project has been designed to contribute to knowledge on the effectiveness of interventions that can be used to prevent youth mental health and behaviour problems. Until recent years the development of programs to support families through the transition into adolescence has been neglected. This is remiss, as there is evidence that a range of youth mental health and behaviour problems may be preventable through interventions through this transition. The overall objective of this project is to evaluate the effectiveness of a multi-level, family intervention designed to promote adolescent health within secondary schools. The intervention will be implemented over the first two years of high school and incorporates both universal components (for all families) and selected components (for families with particular difficulties). The intervention elements have been developed and partially evaluated in work undertaken by the applicant and collaborators over the past five years. To evaluate this intervention a representative sample of 12 Victorian secondary schools will be randomly assigned to intervention and compared to 12 control schools with prior matching on school demographics and student behaviour variables. Intervention processes will be closely monitored and evaluated for impacts on relevant risk and protective factors. Effectiveness will be evaluated by testing whether reductions in youth mental health and behaviour problems were greater for intervention families compared to controls. The evaluation has been designed to test the theory that improvement across the whole secondary school environment can be encouraged by preventing the negative peer influences that can emerge within families experiencing adolescent adjustment problemsRead moreRead less

Summary
Prostate cancer is a major cause of disability and death in Australian men. A number of factors, particularly age and family history, influence the risk of prostate cancer but, in contrast to breast cancer, we don't know what is the risk of developing prostate cancer over a period of time for a man with a specific set of risk factors.

A number of factors, particularly age and family history, influence the risk of prostate cancer but, in contrast to breast cancer, we don't know what is the risk of developing prostate cancer over a period of time for a man with a specific set of risk factors. In fact, while a number of statistical models have been developed that use a woman's risk factor profile to estimate her risk of breast cancer, none is currently available for prostate cancer. We will apply standard statistical methods to existing data from the Australian Risk Factors for Prostate Cancer study and from the Australian Institute of Health and Welfare to develop a prostate cancer risk prediction model. We will test how factor like age, detailed family history, diet, baldness status and possibly previous PSA tests and prostate biopsies predict the risk. After developing the model, we will test the accuracy of the predictions in three ways. First, using existing data from the Australian Prostate Cancer Family Study, we will see whether the number of cases in a group of men is close to the number predicted by the model (calibration). Second, to test whether the model discriminate well men who develop prostate cancer from those who do not, we will collect family trees in a sample from the Melbourne Collaborative Cohort Study. We will use these data also to estimate the optimal cut point: men above this level of risk will be considered at high risk. Third, we will apply the model to existing data from the Dutch Prostate Cancer Family Study (DPCFS) to test whether the optimal cut point identify high-risk men and to validate the model in a non-Australian population. Finally, we will prepare a computer package that health professionals will use as decision-making tool in different scenarios including individual cancer risk assessment, design of prevention trials and targeting prevention programs to high-risk men.Read moreRead less

In our environment of increasing illicit drug abuse and violent crime, there is an urgent need to gain an understanding of the forensic, health and social factors leading to offending by young people in Australia.

Little research has been conducted worldwide looking at the health profile of young people offending across the entire spectrum of seriousness, and we could not find any studies examining this population in Australia. Most reports concern offenders who have received custodial sentences, the most serious end of the offending spectrum. Furthermore, overseas studies are of limited usefulness in the Australian context, as it is difficult to apply observations from communities where the social, ethnic and crime profile may be markedly dissimilar. We propose to interview 450 young people immediately after they obtain their first sentence, usually a community-based order. The problems we will ask about include depression and anxiety, heavy alcohol consumption, heavy use of cannabis and other illegal drugs, deliberate self harm, sexual risk taking behaviour and offending behaviour. We will also ask about the social circumstances, friends and family structure and support. We will then repeat this interview six months later. In addition, we will monitor the participants' compliance with their order, treatment programs they may be on and re-offending until the end of data collection. The study will give us the basis to examine continuity and inter-relationship between problems such as depression and substance abuse, social factors and continued offending. Further, the study will establish a framework to follow-up these young offenders in the medium and long-term. The development of this sound and thorough research program will provide a rational basis for the planning of preventative interventions, aimed at improving the health and welfare and at reducing recidivism in this marginalised and often disadvantaged group of young people.Read moreRead less
Automated Mammographic Measures That Predict Breast Cancer Risk

Summary
Mammographic density (MD) is one of the strongest predictors of breast cancer risk but its impractical measurement prevents its use in a clinical setting. An automated measure of MD would allow screening programs to identify and target women at higher risk of breast cancer which could lead to earlier diagnoses and better breast cancer outcomes. We aim to develop an automated measurement, maximized by its ability to predict breast cancer risk, and applicable to both film and digital mammograms.
Estimation Of Transient Increases In Bleeding Risk Associated With Physical Activity In Children With Haemophilia

Summary
Haemophilia A and B are genetic conditions which affect 1 in 7,000 males in Australia. These disorders cause frequent bleeding due to problems with the clotting factor in blood. Over the past decade there has been a move to administer clotting factor to children with haemophilia in order to prevent bleeds and the consequent damage to joints that occurs when bleeds occur in a joint.

Over the past decade there has been a move to administer clotting factor to children with haemophilia in order to prevent bleeds and the consequent damage to joints that occurs when bleeds occur in a joint. Participation in vigorous physical activity and sport is thought to increase the risk of bleeding. Because of this, children are often given clotting factor prior to playing sport. However clotting factor is extremely expensive. For example, a boy wanting to play tennis three times a week would require three injections of cIotting factor per week at a cost of approximately $250,000 a year. To date there is no good evidence about which physical activities are likely to increase the risk of bleeding. If this information was available clinicians would be able to optimise timing of administration of clotting factor so that it is administered prior to activities associated with high risk of bleeds. Another reason to quantify risk of bleeds associated with activity is to inform decisions about participation in physical activity. Every boy with haemophilia wants to know if he can play sport or ride a skateboard or jump on a trampoline. Informed decisions about participation require accurate estimates of risk. This study will use an innovative design to provide, for the first time, accurate estimates of the risk of bleeding associated with physical activity. This information will form the basis for clinical practice guidelines regarding participation in physical activity.Read moreRead less

The condition tends to run in families and genetic predisposition, in the face of environmental factors, leads to the elevation in blood pressure. My Lab has demonstrated the capacity of a cohort of affected hypertensive sibships we have collected to find loci for essential hypertension at a level that has achieved genome-wide statistical significance and has been published in a leading molecular genetics journal. Moreover, this previous work, which included fine-mapping after finding a suggestive locus following a scan of chromosome 1, not only demonstrated significant linkage, but also went on to compare gene markers between a different cohort of (unrelated) hypertensive subjects with 2 affected parents (and early-onset, moderate to severe hypertension) and control normotensive matched subjects with unaffected parents, to identify a likely candidate gene. This same approach will be used to complete the rest of the genome. The discovery of all of the genes for essential hypertension will be an important prelude to: (1) developing new, more effective treatments, since the gene products responsible will be able to be targetted by novel therapeutics, (2) genotyping individuals early in life in order to advise them what their risk is, and thus allow couselling about lifestyle modification, (3) more logically apply existing treatment strategies according to the volume-neural-vasoconstrctor component of the contribution to high blood pressure.Read moreRead less
